Battery chargers

MSB offers a range of robust, powerful battery chargers, AC-DC switching power supplies and rectifiers in unidirectional and bidirectional designs. The use of bidirectional DC- DC converters makes sense in order to generate an “emergency power supply”, e.g. for emergency ventilation, in the event of a power failure.
Our AC-DC switching power supplies use a high-frequency power conversion topology and optimized magnetic fields to ensure reliability, efficiency and compact dimensions.
For charging batteries without galvanic isolation up to 900 Vdc, the use of bidirectional DC / DC and AC / DC converters for battery charging and for generating emergency power networks is an inexpensive option.

Features:

  • Output power up to 50 kW
  • AC inputs 3 x 400 Vac / 1 x 230 Vac / 50 Hz
    customer-specific variants possible e.g. 1 x 200 Vac 16 2⁄3 Hz
  • DC outputs: 24 Vdc to 900 Vdc or customized
  • PFC (Power Factor Corrected) (EN 61000-3-2)
  • optionally with redundancy and parallel operation
  • Universally applicable for all common battery types
  • EMI filtering to meet the required standards
  • Fire protection according to EN
  • IEC 61373 shock and vibration standards

Application areas:

  • Generation of emergency power networks from the battery
